I can provide a definition of colic, but the search results do not contain information about whether it can be a sign of food allergies.
Colic refers to pain originating from the contraction of the muscular walls of a hollow organ, such as the renal pelvis, biliary tract, or gastrointestinal tract, especially if its aperture is blocked. Intestinal colic is common in infants, particularly those who are bottle-fed, and is characterized by restlessness, continuous crying, and the drawing up of the infant’s legs. Colic may also be associated with enteritis, intestinal tumors, certain types of influenza, or spastic contractions of the bowel caused by lead poisoning.
Treatment focuses on symptom relief and addressing the underlying cause, often involving muscle relaxants like atropine and, in some instances, meperidine hydrochloride.
